SPLIT CLAMP FOR MOUNTING INSULATOR TO FACE OF SIGN OR OTHER OBJECT Filed Oct. 13, 1928 fizusrzfzr fafuczrdf/ oyarz Patented July 28, 1931 UNITED STATES PATENT OFFICE EDWARD F. HOGAN, OF CHICAGO, ILLINOIS, ASSIGNOR TO Q. R. S. DE VRY CORPORA- TION, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS SPLIT CLAMP FOR MOUNTING INSULATOR TO FACE OF SIGN OR OTHER OBJECT Application filed October 13, 1928.

My invention relates tomounting means for an insulator and has for its object the provision of an improved support of this character which is adapted more particularly to hold insulators of the type which are used in connection with gaseous conduction devices suchas the well-known neon signs.

My invention has for its object the provision of a support of this character which will permit adjustment of the insulator throughout a wide range, preferably throughout 360 and which also is so arranged as to permit the insulator which is hollow to properly drain, it being understood, of course, that many of these devices are used out of doors where rain may at times enter.

I will describe my invention more in detail by referring to the accompanying drawings in which Fig. 1 is a sectional view of my improved support showing the same in cooperation with an insulator; and

Fig. 2 is a front view of my improved support mounted in place, the insulator and lamp structure being omitted for the sake of clearness.

Referring to the drawings, I show an insulator 10, the construction of which is more clearly set forth in connection with my application, Serial No. 331,898; filed January 11, 1929. This insulator is adapted to support, for instance, a neon sign shown at 11. The tubing 11 is adapted to project forwardly of the face plate 12 of the completed sign and this face plate is a mounting for my improved insulator support consisting of two complementary halves 13 and 14.

My improved support consisting of the parts 13 and 14 is held in place upon the face plate by the bolts 15. The two halves of my improved support are held together by the screws 16 and 17 shown more clearly in Fig. 2.

It will be noted that the insulator 10 is held in place in my improved support by resting against three bearing surfaces, respectively the bearing surfaces 18, 19 and 20. When the device is first mounted in place, the screws 16 and 17 only loosely hold the parts 13 and 14 together so that the insulator Serial No. 312,291.

10 may be adjusted to any angular position desired so that it may be properly aligned with the incoming electrical conductors. I provide a gasket 21 between the face plate 12 and the front edge of the collar 22 of the insulator to yieldingly but firmly hold the parts in place.

In order to permit proper draining of the insulator, it must be tilted and for this purpose the flange 23 of the element 13 is made thinner than the flange 24 of the element 14. The device as thus constructed is adapted to hold the insulator in any desired position and holds it in such a way that it properly drains. 5

From what has been thus described, the nature of my invention will be readily clear to those skilled in the art and it will also be clear that many modifications may be made without departing from the spirit of 7c my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. An insulator and support for gaseous conduction tubes and the like comprising a tubular insulator having adjacent one end thereof an external annular rib, a pair of complementary supporting pieces having offset shoulders on the interior thereof forming a plurality of bearing surfaces of different diameters encircling said insulator one of said surfaces engaging said annular rib and the other engaging the body of the insulator adjacent said rib, means for clamp- 3;;

ing said pieces together about said insulator,

and means for mounting said support.

2. An insulator and support for gaseous conduction tubes and the like comprising a tubular insulator having adjacent one end as thereof an external annular rib, a pair of complementary supporting pieces having offset shoulders on the interior thereof forming a plurality of bearing surfaces of different diameters encircling said insulator one of said surfaces engaging said annular rib and the other engaging the body of the insulator adjacent said rib, means for clamping said pieces together about said insulator, and means for mounting said support, said last named means including an apertured plate, the aperture of which is smaller than the larger of the interior bearing surfaces formed on said pieces, and a sealing member 5 interposed between said plate and said rib.

In witness whereof, I hereunto subscribe my name this 25th day of September, A. D.

EDWARD F. HOGAN.
